Addax
As the first to introduce advanced composite couplings to the cooling tower industry in 1987, Rexnord Addax is recognized as the benchmark in the industry. The lightweight, advanced composite material design increases critical speed, reduces vibration, and extends bearing life compared to alternative all-steel couplings. Rexnord Addax delivers best-in-class performance and lowest total cost of ownership.
